IMPROVEMENT IN CORN-PLANTER The Schedulev rean-ed to :ln these Letters Patent and makingpart of the same.

To all who/mit may concern:

Be it known that L'lnoMAs DUNoANsoN, of Bu# ford, in the county of Highland, andl State of Ohio, have invented certain new and useful-Improvements in Corn-Planters; and I do hereby declare that' the following is a full, clear, and exact description thereof', reference being had to the accompanying drawings, and to the lettersV of reference marked thereon, which form a part of this specification, and in which- Figure l represents aside elevation of my cornplanter, and

Figure 2, a perspective view of the dropper or distributer. Y

The nature of this invention consists in the employthe reception of the grains of corn to be'distributed er dropped, and operated substantially in the manner hereinafter set forth.

To enableothers skilled in the art to which my invention'appert-ains, to make and employ the same, I will now describe its construction and operation.

In the accompanying drawings- A represents the receptacle or vessel for receiving the corn, which is provided with a chamber passing through its entire length, and made with -a cutting,- edge, and Ypointed on its lower portion, as seen in iig. l.

B is the beam, to which the horses are attached, and embracing the upper part of A, and 4there secured by strips or supports on each side'.

C designates-the handles, secured at their front ends to beam B, and fastened at their rear ends to the pro# jectng ends of the beam B, by means of metal rod d. (See iig. 1.)

D represents the dropper, which consists in constructinga weighted wheel, and providing the same with a cavity, c, on the periphery of the wheel, opposite its weighted portion, and having its bearing on an axle passing through the sides of the upper portion of A.

71 is-abrusb, secured, by means of its handle, tothe inner side of the front part of receptacle A, so that its outer end will rest on the periphery Iof the wheel 0r dropper D, for the purpose of separating the grains of corn.

' g represents a roller or wheel, having its bearings ,in

the outer ends of supports f jQ-Which consist of a horizontal bar, to the upper side of which it is formed with a curved arm, slotted at its inner end, and sliding back and forth, or in a semicircular direction, on a projection secured to each side of the lvessel A, for the purpose of allowing the roller to be raised or lowered, to snit the depth at which it is desired to set the plow or lower end of A. l

m designates a lever, pivoted in the outer eud'of one of the handles, and furnished on its lower vside with a projection, e, to which is attached a metal rod,

e', extending down to and secured to the weighted portion of the dropper D, and, by means of this lever, the dropper can be operated.

An advantage which I claim in so constructing the dropper is," that when the grains of corn have been dropped from it, and the hand removed from the lever m, its own weight will bring the cavity ,in contact with cavity c, arranged and operating substantially as and for the purpose set forth. In testimony that I claim the foregoing as my own, I aix my signature, in presence of two witnesses.
